description = """Gradio demo for <b>NAFNet: Nonlinear Activation Free Network for Image Restoration</b>.
NAFNet achieves state-of-the-art performance on three tasks: image denoising, image deblurring, and stereo image super-resolution (SR).
See the paper and project page for detailed results below. Here, we provide a demo for image denoise and deblur.
To use it, simply upload your image, or click one of the examples to load them. Inference needs some time since this demo uses CPU."""
